An anonymous reader quotes a report from IFLScience: A new paper published in the journal Psychological Science has attempted to define and investigate the subject of free will. By asking participants to anticipate when they thought a specific color of circle would appear before them, something determined completely by chance, the researchers found that their predictions were more accurate when they had only a fraction of a second to guess than when they had more time. The participants subconsciously perceived the color change as it happened prior to making their mental choice, even though they always thought they made their prediction before the change occurred. They were getting the answers right because they already knew the answer. "Our minds may be rewriting history," Adam Bear, a Ph.D. student in the Department of Psychology at Yale University and lead author of the study, said in a statement. The implication here is that when it comes to very short time scales, even before we think we've made a conscious choice, our mind has already subconsciously decided for us, and free will is more of an illusion than we think.
